在名为serialcomm.js的后端文件中,我有一个名为“mode”的变量。我想将模式的值设置为与前端组件 Pacemode() 中的状态“模式”相同的值。如何将 Pacemode 的状态值传递给serialcomm.js 文件?我正在使用 React.js、Node.js 和 SerialPortIO.js。Pacemode.js 代码:/*This navbar component will let the user select which pacing mode interface to display on the page.It will control rendering the view*/import React from 'react';import '../../stylesheets/PaceMode.css';import Button from 'react-bootstrap/Button';// componentsimport AOO from './AOO';import AAI from './AAI';import VOO from './VOO';import VVI from './VVI';import VVIR from './VVIR';import VOOR from './VOOR';import AOOR from './AOOR';import AAIR from './AAIR';import DOO from './DOO';import DOOR from './DOOR';const PaceMode = () => { const [mode, setMode] = React.useState('VOO'); function renderInterface (modeVal) { switch(modeVal) { case 'VOO': return <VOO />; case 'VVI': return <VVI />; case 'AOO': return <AOO />; case 'AAI': return <AAI />; case 'VOOR': return <VOOR />; case 'VVIR': return <VVIR />; case 'AOOR': return <AOOR />; case 'AAIR': return <AAIR />; case 'DOO': return <DOO />; case 'DOOR': return <DOOR />; default: return <h2>{mode} Interface Goes Here</h2>; } }
